Application

8-(3-Chlorostyryl)caffeine has been used as an adenosine A2A receptor antagonist:
  • to study its effects on levodopa (L-DOPA)-induced dopamine (DA) release in rat striatum
  • to study its effect on the nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) activity in macrophages
  • to determine its effects on human umbilical vein endothelial cells (HUVECs)

Biochem/physiol Actions

8-(3-Chlorostyryl)caffeine is a selective adenosine A2A receptor antagonist and monoamine oxidase B (MAO B) inhibitor.

Cannabidiol (CBD) is a natural compound with psychoactive therapeutic properties well described. Conversely, the immunological effects of CBD are still poorly explored. In this study, the potential anti-inflammatory effects and underlying mechanisms of CBD and its analog Dimethyl-Heptyl-Cannabidiol (DMH-CBD) were

A series of substituted 8-styryl derivatives of 1,3,7-alkylxanthines was synthesized as potential A2-selective adenosine receptor antagonists, and the potency at rat brain A1- and A2-receptors was studied in radioligand binding experiments. At the xanthine 7-position, only small hydrophobic substituents were

An adenosine antagonist, 8-(3-chlorostyryl)caffeine (CSC), was shown previously to be 520-fold selective for A2a-adenosine receptors in radioligand binding assays in the rat brain. In reversing agonist effects on adenylate cyclase, CSC was 22-fold selective for A2a receptors in rat phenochromocytoma

Tuberculous pneumonia, necrotic granulomatous lesions, and bacterial dissemination characterize severe forms of mycobacterial infection. To evaluate the pulmonary CD4+ T-cell response during severe tuberculosis, C57BL/6 mice were infected with approximately 100 bacilli of 3 hypervirulent mycobacterial isolates (Mycobacterium tuberculosis strain
